Estimated ultraviolet exposure levels for a sufficient vitamin D status in northwestern Iran
Introduction: Normal exposure to sunlight results in the production of vitamin D in human body, which happens because of the interaction between ultraviolet radiation and cholesterol in skin. Exposure to sunlight is responsible for 90 percent of vitamin D needed for the body. Studies show that Iran is a country with high percentage of lack of vitamin D (83 percent). Based on pr...
متن کاملUltraviolet radiation, vitamin D and multiple sclerosis.
There is compelling epidemiological evidence that the risk of developing multiple sclerosis is increased in association with low levels of sun exposure, possibly because this is associated with low vitamin D status. Recent work highlights both vitamin D and non-vitamin D effects on cellular immunity that suggests that higher levels of sun exposure and/or vitamin D status are beneficial for both...
متن کاملUltraviolet radiation exposure, vitamin D, and cancer.
This paper reviews briefly the evidence for an association between various measures of UV radiation (UVR) exposure and the development of cancer. Issues such as data quality, study design, measurement variation, comparability of studies, and quantification of UV exposure in relation to skin cancer are discussed. A range of exposure, based on skin type, might be appropriate: from 5 min a day thr...
متن کاملCalculated ultraviolet exposure levels for a healthy vitamin D status.
The dangers of overexposure to sunlight have been well publicized, but less attention has been given to an acknowledged benefit of exposure to UV radiation; that being the cutaneous synthesis of vitamin D3. Here we define a standard vitamin D dose on the basis of recently recommended requirements for vitamin D that take account of its risk reduction role in a variety of diseases, and present a ...
متن کاملA Review of Evidence that Ultraviolet-B Irradiance and Vitamin D Reduce Risk for Cancer
The solar ultraviolet-B (UVB)–vitamin D–cancer hypothesis was proposed in 1980 and has been actively investigated since then. The strongest evidence is from ecologic studies that use indices of solar UVB doses with geographic data on cancer incidence and/or mortality rates. Good evidence also comes from observational studies for breast and colorectal cancer incidence as well as survival rates f...
